If violating a restraining order is a misdemeanor or other crime, which it certainly is if bail is set, then the burden of proof goes the other way at trial (which we aren't at yet).
The state must prove he sent it (probably, I am assuming, knowingly --- I doubt that fat-fingering is enough given due process requirements), and they must prove it beyond a reasonable doubt.
